Answer 3

Calculating the Number of Postcards in Each Album

To calculate the number of postcards in each album, we can use a system of equations based on the information provided.

Let's denote: - x as the number of postcards in the first album - y as the number of postcards in the second album - z as the number of postcards in the third album

We are given the following information: 1. In the first and second albums, there are 84 postcards in each. 2. In the second and third albums, there are 127 postcards in each.

We can express this information as a system of equations: 1. x + y = 84 (Equation 1) 2. y + z = 127 (Equation 2)

We can solve this system of equations to find the values of x, y, and z.

Solving the System of Equations

To solve the system of equations, we can use the substitution method or the elimination method. Let's use the substitution method.

From Equation 1, we can express x in terms of y: x = 84 - y (Equation 3)

Substitute the value of x from Equation 3 into Equation 2: (84 - y) + y = 127 84 + y - y = 127 84 = 127

This equation does not hold true, which indicates that there might be an error in the given information. The provided information does not seem to be consistent, and as a result, it's not possible to accurately determine the number of postcards in each album based on the given information.
